MIETAL WOOL AND FIBER MIXTURE.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed January 13, 1906, Serial No. 295,855. Renewed October 5, 1907. Serial No. 396,022.

To all whom it may concern:

Be it known that I, ALFRED SHEDLOOK, a citizen of the United States, residing in Jersey City, county of Hudson, State of New Jersey, have invented an Improved Metal Wool and Fiber Mixture, of which the followin is a specification.

he roduct constituting the subject-matter of t is invention comprises a mixture of absorbent fibers, such as those of cottonwaste, and filaments of metal-wool, wherein the absorbent fibers are laid in arallelism, or substantially so, with the meta filaments,

the assemblage of fibers and filaments being then adapted to be rolled or massed into aggregations of desired size. The primary purpose for which this product is intended is as a substitute for cotton-waste for packing journal boxes of cars and locomotives.

The metal-wool filaments may be formed as described in my application N 0. 295,853,

filed January 13, 1906 and may or may not be crimped as described in my application No. 295,854, filed January 13, 1906. That is 'to say the filaments may be produced byv severing a rolled thin sheet of metal in lines parallel, or substantially so, with the grain of the metal. The thickness of the filament-s is the same as the thickness of the metal sheet fromwhich they are cut, their width being determined by the s aces between the parallel cuts. When a rolled thin sheet of metal is divided into a plurality of filaments by cuts parallel, or substantially so, withthe rain of the metalthe rain is not materia ly disturbed. The a vantages of a metal wool of this character are: that it does not crumble or break, each filament retaining the characteristics of the metal in the original sheet, although the metal is somewhat hardened by the shearing operation and the filaments have, therefore, the elastic or resilient qualities of the sheet from which they are out, such qualities beingl slightly em hasized by the o erations to W ich the meta is subjected. ilaments of this character may be readily distinguished under a glass, or even by the naked eye, from metal-wool filaments heretofore produced by laning or turning o erations. As described inmy application 0. 295,854, the metal filaments may be crim ed or corrugated transversely of their lengt h. In practice, I have made this metal wool from metal sheets of from three to nine one-thousandths of an inch thickness, the filaments bein cut to awidth of about twenty one-thousandt bs of an inch.

The terms, arallel or substantially so: and substantial parallelism; are intended to convey the meaning that the filaments of the metal wool and the fibers of other material have the same general direction, 2'. e. are in general arrangement longitudinal with respect to each other, in contradistinction to t e heterogeneous mixture heretofore made of such material.

The fibers of the cotton waste or other absorbent material are relatively straight and in parallelism when they and the correspondingy arranged filaments are first brought together as shown in Fig. 3, and such general arrangement is not obstructed when such a group of fibers and filaments is massed or bunched as in Fi 4. The ordinary operation of combing may be employed to produce such arrangement of the fibers.

In the accom anying drawings: Figure 1 shows a straig it metal filament: Fig. 2 shows such filament crimp'ed or transversely. corrugated; Fig. 3 shows a number of metal filaments associated with fibrous strands or fibers, the filaments and fibers lying in the same general direction: and Fig. 4 shows a mass or aggregation of filaments and fibers formed by bunching such a collection thereof as is shown in Fig. 3.

In i 1, a, represents one of the strai ht metal aments, and Fig. 2 shows such a ament with crim s or transverse corrugations a. In Fi 3 t e filaments a are disposed in substantia lystraightparallellines, somewhat separated: and the combed, or relatively strai ht fibers b are superposed upon them.

The fiat masses or layers thus formed may be bunched or; rolled into masses of desired size,

one of which masses is indicated in Fig. 4.

i The thickness and width of the metal filaments are determined, respectively, by the stock used and the out: and may be such as to ada t the material to desired uses. I

have a ove given dimensions of filaments produced by me. They may, however, be

made of materially smaller dimensions if de- In testimony whereof, I have hereunto aired. subscribed my name.

I claim w r A mixture of 1netal-w0ol and absorbent ALFRED SHEDLOUX' fibers in which the general arrangement of Witnesses;

fibers and metal filaments is longitudinal with L. F. BROWNING,

respect to each other, EDWARD O. DAVIDSON.
